c# - 在 C# 中列出目录时如何过滤文件

Question

我正在尝试过滤方法的输出，因此只会返回带有“FF-”前缀的文件。

我的代码如下:

 DirectoryInfo dinfo = new DirectoryInfo(@"C:\Windows\system32\tasks");
            FileInfo[] Files = dinfo.GetFiles("*.*");
            foreach (FileInfo file in Files)
            {
                listBox1.Items.Add(file.Name);
            }

Answer 1

像这样？

FileInfo[] Files = dinfo.GetFiles("FF-*.*");

Directory.GetFiles Method

引用:

* - Zero or more characters.  
? - Exactly zero or one character. 

For example, the searchPattern string "*t" searches for all names in path ending with the letter "t". The searchPattern string "s*" searches for all names in path beginning with the letter "s".
